“It’s taken months to get to this moment,” Winfrey said. “It involves a two-time Academy Award winner, a sharp object, and me.”

The media mogul cut nine inches off Hillary Swank’s hair, as part of a charity effort airing tomorrow on her talk show. Swank’s hair will be donated to Pantene Beautiful Lengths – a campaign that encourages people to grow, cut, and donate their hair to create real-hair wigs for women who’ve lost their hair due to cancer.

“I’ve been growing it for the last six months to donate my hair,” Swank says. “I’ve been taking a lot of vitamins and taking really good care of it, knowing that it would go to a woman in need.”
